Difficult to believe after all this time that the Italians have not finished their investigation.
AFAIK, the most recent reference to the investigation on the ANSV website is as follows:
"Italian “Agenzia nazionale per la sicurezza del volo” (ANSV) informs that next week, from 9 to 13 February 2009, at GE Aviation facilities in Cardiff (Wales - UK) will be performed the engines teardown. Aim of the activity, which will be conducted under the control of ANSV officials (head of Investigation Department and the investigator-in-charge), is to verify in details the damages suffered by both engines in order to better understand the engines performance following the birds ingestion (as much as 90 starling impacted against aircraft structure).
Representatives of all air accident investigation boards involved in the ANSV technical investigation, conducted as per Annex 13 ICAO procedures (NTSB, BEA France, AAIU Ireland), will be attending the operation, together with personnel from the operator, FAA, EASA, Boeing and the engine manufacturer (CFM).
As much as 20 people will be attending the operation; there is such similarity with the A320 which ditched into the Hudson River on January 15th, 2009.
Being the same engines involved in both events, the teardown activity is of utmost importance in order to gather data as to see whether any commonality may exist between the two events."
